I agree with the consensus that you need a lawyer to navigate you thru this, but if you fire them without their being made aware of their actions constituting harassment you are liable. Further if you do not conduct an investigation that involves all parties you are liable. I have seen more grey area cases where a complaint is filed and it comes out she is married, things went to far and now it gets walked back as harassment (usually due to a husband finding a chat log). Not saying this is what's happening here but that's the point you don't know, you have one side of the story and acting on one side of the story puts you in a bad legal position. Further harassment requires a warning that the actions are not appropriate and constitute harassment (documented) by either the individual or a supervisor and a second violation before it is actionable. This often gets construed with sexual assault which is actionable immediately. Basically the TL;DR is "get a lawyer before you do anything".
